System

The corridor would cross determined and claimed native title across most of its route. Traditional Owner partnership is structural to the concept, not a late-stage approval. See Country for principles, the illustrative NNTT table, and the engagement sequence.

The site’s position: no element of the corridor advances onto Country without free, prior and informed consent from the relevant Traditional Owners.

Single-axis tracking solar in the inland belt. 40–55 MW/km² installed density, 22–24% annual capacity factor^[1]. Sized around downstream consumption, not wholesale export. Modules commodity, tracking systems commodity, EPC market mature in Australia (Downer, UGL, GenusPlus, others).

Reference build: 1–2 GW at first node, standardised block design repeated at subsequent nodes.

Battery storage at multiple durations. Short-duration BESS (1–4 hr) for daily shaping and evening peaks. Long-duration BESS (8–12 hr) or alternative chemistries for winter industrial firming.

The math: a 1 GW continuous industrial load, firmed on solar+BESS alone to 99% availability, requires a storage-to-generation ratio of 6–10 GWh per GW installed solar^[2]. The upper end reflects winter trough dispatch, which drives storage sizing more than annual energy balance.

Latency-tolerant compute campuses at 100–400 MW reference scale — not multi-gigawatt single facilities. The workload split is deliberate: training, batch, sovereign hosting, HPC. Hyperscaler cloud regions, inference, and low-latency services stay coastal.

See the workload fit zone on The Case for the split in detail.

Processing where energy is a decisive input. Screen: energy share of operating cost above 25%.

• Critical minerals: lithium hydroxide, magnesium, refined alumina where local minerals justify it
• Battery supply chain: precursors, cathode materials
• Selected chemicals: urea, ammonia (for domestic use, not export)
• RO desalination at industrial scale

Excluded: light manufacturing, general assembly, anything logistics-flow-bound. The corridor is not an industrial policy in itself — it hosts industries for which its cost structure is decisive.

Water is a system challenge, not an absolute barrier. Three sources: desalination (most likely Spencer Gulf or Shark Bay feedstock), groundwater within sustainable yield, and recycled process water.

Conveyance is the hard problem. Moving water 1,000–2,000 km inland costs 1.5–2.5 kWh/m³ — a TASC extrapolation from the Goldfields & Agricultural Water Supply Scheme’s pumping energy — on top of the 3 kWh/m³ for seawater reverse osmosis (SWRO)^[3]. Corridor generation makes the pumping energy cheap; corridor design still has to sequence water carefully around industrial demand.

Water is sized to industrial and DC needs first. Community water uses follow once industrial scale is established.

Roads (Goldfields Hwy, Great Central Rd, Stuart Hwy, Barkly Hwy, Landsborough Hwy), rail (Adelaide–Darwin, Mount Isa line), fibre (Telstra terrestrial, Vocus, Indigo cable landings via Perth), freight services (Toll, Linfox).

The corridor deliberately shadows existing freight infrastructure for construction access and operating logistics.

The order matters — productive capability comes first: energy, water, compute, logistics, and industry. Communities grow where those fundamentals make long-term sense.

Existing communities along the route are the near-term workforce and service base — Kalgoorlie, Leonora, Alice Springs, Tennant Creek, Mount Isa, Longreach and settlements between. Long-term node viability depends on these communities being beneficiaries of the build, not bystanders to it.

New communities are only justified at large industrial nodes where sustained employment demand exists. Housing follows durable productive activity; the corridor does not build speculative towns.
